C M had to travel to Germany for a family issue, very personal and very sad.
He is still very much at Emirates. The next person of high rank to be leaving will most likely be Sir Tim, although this is not officially announced just yet.
C M is very much a man of principle it appears and seems to be able to detect where the rot is most embedded in the company. With a management to pilot communication statistic of well below 10%, he clearly sees that it's not the pilots who need changing/briefing here. C M is very open to communication and is willing to take appointments to discuss any important issues you might have been pondering.
